Can't Image with PXE boot

Question

Every thing was working fine until recently. I've tried to find an answer to this but so-far haven't run in to the answer.

Here are the details. I'm trying to image and HP DeskPro 600 and I can get it to PXE boot but when the windows splash screen comes up it does not proceed to the MDT login screen to start the process. If I use a USB stick that has the boot IOS
on it I can get through the complete script and start the imaging process but it hangs when it come to formatting the disk. I'm wondering it the issue might have something to do with UEFI. We do disable that function on our computers before we
image and like I said it has worked in the past. Currently I'm moving WIM file to another server that has MDT 2013 installed and they seem to work fine on that server. So, do you thing an update from 2012 to 2013 would solve the issue I'm
having? Or if someone has had this issue and has a fix for It I would appreciate some help in this area.

So one of the other steps I'm trying is to delete two folders in MDT that I setup for drivers that I wanted the boot PE to use. The only thing I did wrong is that I loaded windows 8.1 drivers in the folders. I did disable them and tried to run
but that wasn't the answer. Now I'm just removing them.

I'm actually having a similar problem here. Although I was able to actually get a HP 600 to boot to pxe, I cant get a HP DC6300 too. I get to this screen: http://i.imgur.com/gx9xzoN.png. This is all with the x32 LightTouch image. It boots to the x64.

It seems like your issue is just the reverse of mine. I'm not booting to the 32 bit LightTouch on the DC600 and I'm not having any issue with other models of the HP computer.
They all seem to image fine. It's just the ProDesk that is giving me stress. But just to cover all the basses I downloaded the latest storage driver and will try that out to see if it works.

Everything else I have tried has failed to fix the issue so-far.

What version of MDT are you running their? I've been thinking that moving to 2013 would fix this issue so that's why I ask.

With respect to the F8 issue, we may be talking about different things.

If you only get as far as the kernel bootstraper screen, as illustrated by Gut:

using AMD class machines, I rarely encounter problems with modern (Windows 8.x logoed) machines.

If you are talking about the screen when MDT boots into WinPE, and you can see the mouse move around, you should be able to press F8 to get into the cmd.exe window, again, if you don't see the mouse, you can't do this.
